What it detects

This rule detects the Visual Studio build engine spawning a command interpreter or PowerShell which is characteristic of a malicious pre-build event script. The GitVenom campaign abused the Visual Studio PreBuildEvent to launch a hidden batch file that deployed cryptocurrency-stealing malware when a victim compiled a trojanized project. Detecting build-time command execution catches supply chain compromise before payloads are staged.
